1. Halnn Tools CBN Hard Turning 20CrMnTi Hardened Steel materials Gear with Halnn WNGA PCBN inserts

Halnn Toosl is one of the manufacturers of super-hard tools. Since its inception, Halnn Toosl has developed cubic boron nitride inserts for high-hardness and difficult-to-machine materials. Gears are one of the common parts. There are special tool grades for hard gears.

In the case where the cubic boron nitride insert is not recognized, many of the grinding processes have existed until today. However, with the improvement of the performance of CNC machine tools and the increasing focus on efficiency of gear manufacturers, some companies have improved the processing technology and adopted the car grinding process to achieve hard turning and improve production efficiency.
